use the periodic table to select the element that best fits each of the following descriptions. which solution below most likely shows a vivid color? potassium chloride nickel chloride hydrogen chloride lithium chloride done

Answer

Explanation:

Step1: Recall metal - ion color properties

Transition metal compounds often show vivid colors due to d - orbital electron transitions.

Step2: Identify transition metal

Nickel is a transition metal. Nickel chloride ($NiCl_2$) can have a green color in solution. Potassium, hydrogen, and lithium are not transition metals. Their chlorides (potassium chloride $KCl$, hydrogen chloride $HCl$, lithium chloride $LiCl$) are typically colorless in solution.

Answer:

nickel chloride
